摘　　要：为同时解决炸药的能量输出和力学强度问题,研发了一种以RDX为基的新型复合炸药KD-1,用水下爆炸压力测试系统研究了KD-1炸药的能量输出特性。结果表明,KD-1炸药的冲击波压力峰值和冲击波比能都比RDX有所提高,冲击波压力峰值是RDX的1.1倍,爆热是RDX的1.3倍。用万能实验机测试了KD-1的抗压力学性能,得出其抗压强度为6.82M Pa,破坏应变为4.3%。In order to simultaneously solve the energy output and mechanics intensity of explosives, a new composite explosive KD-1 was prepared. The energy output characteristics of the composite explosive was investigated by underwater explosion pressure test system. The results show that the peak pressure and specific energy of shock wave of KD-1 explosives are higher than those of RDX. The peak pressure of shock wave of KD- 1 explosives is 1.1 times of RDX, and explosion heat 1.3 times of RDX. The pressure resistance performances were tested by an omnipotence experimentation machine. The results show that the compressive strength of KD-1 is 6. 82MPa and failure strain 4.3%.
